Possible airfilter for 2pdr Carrier
 

Can someone help to confirm if this is an airfilter for a 2pdr Carrier. I can't find any part numbers on it but it looks identicle to the one shown in the illustrated parts manual.

It originaly came with my Carrier when I got it. I believe my hull had been converted to a 2pdr carrier way back as some of the things done are the same as on other known 2pdr Carriers.

Let me know what you think?
